SPECIFICATION forming' part of4 Letters Patent No.` 740,425, datedOctober 6, 1903.

.tppncaitn ined August so, 1902. serial-nt. 121.598. on man To a/ZZwhom, t may concern:

Be it known that I, CORD EDUARD JOHANNES GRUBE, residing atAlt-Rahlstedt, near Hamburg, in the Empire of Germany, have inventedcertain new and useful Improvements in Lamp-Burners, (for which I haveapplied for a patent in Germ-any, and which application is datedFebruary 5, 1902,) of which the following is a specification.A

This invention relates to improvements in lamp-burners in which a wickis employed, and has for its object to prolongthe life of the wick, toincrease the efficiency of the wick by preventing the charred part ofsaid wick interferingwith the iiow of the oil or other combustiblehydrocarbon employed, to readily extinguish the flame when the wick islowered, and to limit the height to which the wick can beraised. V

Various oil wick-burners have been provided with a cap covering one sideand the rear surface of the wick and arranged so that the cap was movedby and with the wick upon the upward movements thereof until the cap wasarrested by stops above and below. The object of these devices was tocause the wick to burn only upon the exterior, to limit the movement ofthe wickiwithin bounds which were found to be most suitable, and toextinguish the light automatically upon turn-ing down the wick. I InAthese devices, however, the cap upon turning down of the'wick could Thewick would then withdraw from the cap, and was thereby damaged at itsupper end. These prior devices, moreover, .were all of specialconstruction and adapted to only cerf tain makesrof burners. Y

The protecting-ringer wick-cap forming' the present invention is soconstructed and arranged that while it is restricted in its upwardmovement it can move freely in the downward direction, so that thewick-cap upon turning down the wick is not torn away from the latter,but sinks with it into the wick-tube. In'this manner damage to the upperedge of the wick is prevented and the desired position of the wickmay-be maintained. Furthermore, the' 'wick-cap is such that it can bereadily adapted and applied to any of the ordinary types of oilwick-burners now on Vthe market. The wick-cap is so proportioned that itfits the space between the wick-tubes, and consequently will serve as anextinguisher upon turning downv the wick, although it does not, however,rest upon the wick-tube, but can follow the wick into the tubes.

The present invention therefore consists in the novel burner attachmenthereinafter described and claimed, and illustrated in the drawings, inwhich- Figure l is a vertical section of a burner with my inventionapplied. Fig. 2 is a transverse section' on line 2 2, Fig; 1. Figs. 3,4, and are detail sectional views, enlarged, showing the attachment indiiferentpositions.

f In said drawings, A designates abnrner of the Argand type, B thewick-tube, C the wick, and D the dame-deflector, all of which maybeconstructed as in the commonly-known Argand burners. My attachmentconsists of a wick cap or ring E, which lits loosely between the innerwall of the wick-tube and the wick and is provided with an annularoutwardly-projecting flange e on its upper end, whichrests upon andextends across the top edge of the wick. This wick-cap is adapted tofollow the movements of thewick as the latter is raised or lowered. Whenraised, the outer side of wick between the outer wall of the wick-tubeand the flange of the wick-cap is exposed for the combustion of thehydrocarbon, thus reducingthe liability of a charred part at the topofthe wick interfering with lthe iiow of hydrocarbon. v

When the wick islow'ered, wick-.cap descends therewith and the aforesaidflange practically closing the space between the inner and outer wallsof the wick-tube rapidly extinguishes the dame.

The extent to which the wick can be raised kis limited by a stop carriedby the fixed part ICO Having thus described my invention., what Itherefore claim as new, and desire to secure by Letters Patent thereon,is-

In combination, a burner having an annu- 5 lar wick-tube, a wiok, awick-cap tted loosely wick, so that the wick on being turned down is notdrawn away fromthe wiok-eap, and means to limit the upward movement ofthe wick-cap, all substantially as and for the pnr- I5 pose described.
